Houston-area woman shoots, kills firefighter neighbor

A Houston firefighter was shot and killed by his 64-year-old next-door neighbor who claimed the man was trying to break into her Montgomery County home.

The woman said she had no idea Samuel Keen, 27, was a firefighter and her next-door neighbor.

At around 9:30 p.m. Monday, the woman said she heard a man fumbling around the front gate of her Porter Heights home. According to deputies, it sounded to her like he was trying to break in. She was home alone, so detectives say she grabbed her protection -- a revolver.

"At the time, she again told him to leave and that she was armed," Sgt. Dan Zientek of the Montgomery County Sheriff's Office told KPRC-TV in Houston.
